description: >
|
|
Detects container escape attempts by analyzing namespace configurations, privileged
|
|
container checks, dangerous capability assignments, and host path mounts using the
|
|
kubernetes Python client. Identifies CVE-2022-0492 style escapes via cgroup abuse.
|
|
Use when auditing container security posture or investigating escape attempts.

# Performing Container Escape Detection
|
|
|
|
## Instructions
|
|
|
|
Audit Kubernetes pods for container escape vectors including privileged mode,
|
|
dangerous capabilities, host namespace sharing, and writable hostPath mounts.
|
|
|
|
```python
|
|
from kubernetes import client, config
|
|
config.load_kube_config()
|
|
v1 = client.CoreV1Api()
|
|
|
|
pods = v1.list_pod_for_all_namespaces()
|
|
for pod in pods.items:
|
|
for container in pod.spec.containers:
|
|
sc = container.security_context
|
|
if sc and sc.privileged:
|
|
print(f"PRIVILEGED: {pod.metadata.namespace}/{pod.metadata.name}")
|
|
```
|
|
|
|
Key escape vectors:
|
|
1. Privileged containers (full host access)
|
|
2. CAP_SYS_ADMIN capability
|
|
3. Host PID/Network/IPC namespace sharing
|
|
4. Writable hostPath mounts to / or /etc
|
|
5. Docker socket mount (/var/run/docker.sock)
|
|
|
|
## Examples
|
|
|
|
```python
|
|
# Check for docker socket mounts
|
|
for vol in pod.spec.volumes or []:
|
|
if vol.host_path and "docker.sock" in (vol.host_path.path or ""):
|
|
print(f"Docker socket exposed: {pod.metadata.name}")
|
|
```
